The use of in-vehicle technology influences driving behavior and impacts traffic safety. In this study, driving errors made while using (and not using) a mobile phone, a navigation system, and cruise control were investigated. The sample consisted of 15 experienced drivers who twice drove the same route - once while using IVT (in-vehicle technology) and once without using IVT. Drivers were observed using the Wiener Fahrprobe method. Drivers using cruise control drove too fast less often, but too slow (according to observers' opinion) more often and broke more traffic rules. They also stayed too long in the left lane without overtaking and maintained too short of a distance to the car ahead. When drivers used a mobile phone, they made errors at intersections or obstacles and made mistakes using turn indicators; however, they less often drove too close to the car ahead, and also drove slowly. When using a navigation system, drivers forgot to use turn indicators, made mistakes when they did not know where to go, and even drove through a red light while concentrating on the navigation technology.
